Samsung phones: Because of a firmware bug, they may report extreme battery consumption for GPS Status even if it is not running at all (other programs using sensors are affected too). This is harmless and no power is consumed! Just ignore it and let’s hope that a future firmware upgrade will fix this on your phone.

Droid 3: The initial Droid 3 firmware does not implement the satellite status API so you will not see the satellites and the signal strength bars. The rest of the features should work properly.

Motorola phones: On some phones, turning your phone to airplane mode will turn off the GPS receiver, too. This is a hardware limitation.
